This reverts commit 560d8b833e.
This change created a potential race between key refresh queries and
root zone priming queries which could leave the root name servers in
the bad-server cache.
4773. [bug] Keys specified in "managed-keys" statements
can now only be used when validating key refresh
queries during initialization of RFC 5011 key
maintenance. If initialization fails, DNSSEC
validation of normal queries will also fail.
Previously, validation of normal queries could
succeed using the initializing key, potentially
masking problems with managed-keys. [RT #46077]
4768. [func] By default, memory is no longer filled with tag values
when it is allocated or freed; this improves
performance but makes debugging of certain memory
issues more difficult. "named -M fill" turns memory
filling back on. (Building "configure
--enable-developer", turns memory fill on by
default again; it can then be disabled with
"named -M nofill".) [RT #45123]
4762. [func] "update-policy local" is now restricted to updates
from local addresses. (Previously, other addresses
were allowed so long as updates were signed by the
local session key.) [RT #45492]
4757. [func] New "dnssec-cds" command creates a new parent DS
RRset based on CDS or CDNSKEY RRsets found in
a child zone, and generates either a dsset file
or stream of nsupdate commands to update the
parent. Thanks to Tony Finch. [RT #46090]
4751. [func] "dnssec-signzone -S" can now automatically add parent
synchronization records (CDS and CDNSKEY) according
to key metadata set using the -Psync and -Dsync
options to dnssec-keygen and dnssec-settime.
[RT #46149]
4750. [func] "rndc managed-keys destroy" shuts down RFC 5011 key
maintenance and deletes the managed-keys database.
If followed by "rndc reconfig" or a server restart,
key maintenance is reinitialized from scratch.
This is primarily intended for testing. [RT #32456]
4749. [func] The ISC DLV service has been shut down, and all
DLV records have been removed from dlv.isc.org.
- Removed references to ISC DLV in documentation
- Removed DLV key from bind.keys
- No longer use ISC DLV by default in delv
[RT #46155]
4724. [func] By default, BIND now uses the random number
functions provided by the crypto library (i.e.,
OpenSSL or a PKCS#11 provider) as a source of
randomness rather than /dev/random. This is
suitable for virtual machine environments
which have limited entropy pools and lack
hardware random number generators.
This can be overridden by specifying another
entropy source via the "random-device" option
in named.conf, or via the -r command line option;
however, for functions requiring full cryptographic
strength, such as DNSSEC key generation, this
cannot be overridden. In particular, the -r
command line option no longer has any effect on
dnssec-keygen.
This can be disabled by building with
"configure --disable-crypto-rand".
[RT #31459] [RT #46047]
Stage 2 - synthesis of records from wildcard data.
If the dns64 or filter-aaaa* is configured then the
involved lookups are currently excluded. [RT #40138]
4721. [func] 'dnssec-signzone -x' and 'dnssec-dnskey-kskonly'
options now apply to CDNSKEY and DS records as well
as DNSKEY. Thanks to Tony Finch. [RT #45689]
